"The text [of Les blason] is essentially a recital of the values, virtues, and magical properties of gemstones in general...some sources of materials are given, but mostly the comments dwell upon the curious lore associated with the gemstones...Whiâle little new is to be found therein, this appears to be the first gemological treatise of importance to be published in France in the vernacular."--Gemology, J. Sinkankas, entry no. 6476.

Error in foliation: leaves 9-14 numbered 5-10; leaf 16 and 19 numbered 14 and 16 respectively; leaf 33 numbered 30; leaves printed on both sides.
